HORSE-DETA'CHER.

BREGIFICATION forming part of Letters Patent No. 305,858, dated September 30, 1884.

To an wlwm' it Hwy concern/.-

Be it known that we, JOHN E. STEVENSON and JosnPH FORSYTI-I, both of Brighton, in the county of Tipton and State of Tennessee, have invented a new and Improved Horse Detacher, of which the following is a full, clear, and. exact description.

Our invention consists of an improved contrivauce of tracehooks and means for unhooking the traces therefrom whenit becomes necessary to detach the horses, the object of which is to provide simple, efficient, and reliable means of escape from the horses when they beconic uncontrollable, as hereinafter fully described.

Reference is to be had to the accompanying drawings, forming part oi'this specification, in which similar letters of reference indicate corresponding parts in all the figures. V

Figure 1 is a plan view 01' an evener and whiiiietrees provided with our improved detaching apparatus. Fig. 2 is a front elevation of the same, and Fig. 3 is a side elevation.

Ne make the trace-hooks to consist of a shank, a, rigidly attached to the whiiiietree b at one end, so as to project directly forward, and having an eye, 6, at the frontend, and a hasp-stud, f, near the whiilletree,and projecting downward, together with a hasp, {1, also having an eye, 71, by which it is jointed with eye 6, and also having at slot i'orengaging with the stud], to which it is secured by a'split key, j, inserted through the stud below the beep, so that when the key is pulled out of the stud the hasp will drop down and release the trace. For pulling out the keys we connect the keys of each whiffletrce to a roller, k, or it may be a roclelever located at the center of the whiffletrce, and connected to the end of a rocker'shaft, l, fitted in suitable bearings on the clevis m, extending back to the evener q, and having a lever-arm, n, reaching toward-the center of the evener, and connected with a chain, 0, extending up to a position where the driver can reach it conveniently for pulling up the levers to draw out the keys Application filed April 25. 1394. (No model.)

when desired. The weight of the lever-arms keeps them down, so that there is no tendency to pull out the keys by any action of the parts in the ordinary working of the vehicle; but the pulling of the levers up by the chain will not fail of pulling out the keys, which frees the hasps 9, so that they will open at once by the influence of their weight, the shocks of the gear in motion, and also by some tendency of the pull of the traces, which are thrust downward to some extent by the curves of the shank a. back of the 03 e e.

Thekeysj are connected, by cords, wires, or chainsp, as preferred, with the upper and lower sides of the pulleys 7:, respectively, according as the directions in which they pull when turned.

It is not essential to employ pulleys for detaching the keys, as lever-arms extending up and down from rockers Z will serve the same purpose. 1

' Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. The improved safety trace-hooks for detaching apparatus, consisting of shank a, attached at one end to the whii'iietree, and having an eye, a, in the other end, connecting with a hasp, g, and also having a stud, f, extendin g downward near the whii'tlctieewit-h which the hasp connects, and to which it is secured by a split key, 9', substantially as described.

Theconibinationofalever-arm,n, rocker Z, and pulley k, or equivalent device, with tracehooks consisting of shank c, hasp g, and hasp-stud f, said hasps being secured to the haspstuds by split keys, and the keys being connected to the pulleys or equivalent devices, 8 5 and the levers-4nd rockers being arranged with relation to the evener and whiilietrees, substantially as described.
